What happens if you sleep shirtless on a hot night?

While sleeping naked may seem like the ideal way to keep cool on sweltering summer nights, a British psychologist warns that sleeping naked could be causing you to lose sleep.

I advise against sleeping naked, because the sweat then sits on your skin instead of being absorbed by the fibers of your clothes and cooling you down, explains sleep expert Suzy Reading, a UK-based health coach, according to the New York Post .

Instead, she recommends wearing "loose, airy, lightweight clothing made of natural fibers," preferably cotton, and preferably in light colors.

Tips for good sleep

Avoid spicy or greasy foods, as they increase body temperature and make it difficult to sleep.

Be careful with fermented foods or soy sauce, tofu, citrus fruits, cured meats and aged cheeses. These contain the amino acid tyramine, which can increase brain activity and make it harder to fall asleep, explains Suzy Reading.

Reading experts also advise avoiding alcohol before bed, as it reduces sleep quality and causes "waking up intermittently", which can leave you exhausted in the morning.

If you share a bed, using separate blankets can ensure you and your bed partner get a good night's sleep.

Taking a bath 1-2 hours before bed has been scientifically proven to help you sleep better.

A good tip is that taking a bath before bed can help you fall asleep easier.

Taking a bath 1-2 hours before bed has been scientifically proven to help you sleep, explains Reading. It works by drawing your core heat to your extremities, where it is released.

"It's the body's heat dissipation after bathing that promotes sleep," Reading added, according to the New York Post .
